For a long time, due to the ignorance of physiological knowledge of lightheadedness, dizziness, fainting, heart palpitations, and so on,, psychological illusion in people’s sleep generated by such physical symptoms i.e the nightmares , flying dream and falling dream really has puzzled the psychologists,  One without flying experience in the daytime would dream of flying; One without falling experience in the daytime would dream of falling; one without terrible experience in the daytime would have terrible nightmares. Such examples are the major evidence for Freud and other oneiromancy masters to prove the causes of dreams are very complex and that dreams have special meaning. They are also the major cause why countless people believe various ridiculous oneiromancy theories with mysterious color put forward by Freud and other oneiromancy masters. But, the latest researches of Chinese scientists show these dreams are of no any special meaning and the causes of dreams are very simple, viz. they are the reactions of the objective things in the minds. As Germany’s well-known psychologist William Wundt’s view of “the most common causes of the dream are indigestion, heart pulsation(palpitations or flustered),difficulity in breathing, aswell as such symptoms.” For instance, students dreaming the examination before the pre-examination, is caused by the things about examination. The sense of urgent urination would give rise to the dream of looking for the toilet. In a cold night, thin quilt would cause one to dream the clothes are socked by water and thus make him/her feel cold. Similarly, the nightmares are mainly caused by several palpitation feelings . When palpitations occurs, people will have two most common feelings: one is tachycardia cause a feeling of seeming to be chasing ; the other is bradycardia or premature beat cause the feeling of heart suspension or heart sinking. Therefore, people in sleep accordingly will have the two most common nightmares : one is dream of being chased (occasionally hunting other people) ; the other is dream of flying in the air or dream of falling down.

All this is sensible enough, but how do you test it?

Perhaps nightmares are a gift to us from a benevolent deity to remind us that the world of s**t we wake up to every morning isn't as bad as the world of s**t we've just left behind in our dreams!

The current research regarding dreams is sketchy. We dream at any stage of sleep although most during REM sleep and REM sleep itself varies in duration throughout the night. What we experience, particularly traumatic events, can have a profound impact on our dreams as can such elements as alcohol and drugs. But, from a therapeutic perspective, we can alter our dreams. Image rehearsal training (IRT), for example, is a process of rescripting nightmares into more pleasant dreams by literally rewriting the part of the dream that is unpleasant and practicing the new script during waking hours.

All nightmares are caused by palpitations ,nightmare has nothing to do with during REM sleep.

I must not have palpitations, whatever those things are, cause I don't have nightmares.  Sometimes I dream I am doing a kind of flying but that is most pleasant.  Usually I just dream a nice place, but nothing much happens except I walk around and take it in.

Isn't it possible that palpitations during sleep are caused by nightmares?

When I was younger and use to have sleepovers with my cousins at my grandmas house, they all use to say what they were gonna dream about, like they could control it. I never said what I was going to dream about because I dont think you can control the dream world....especially at that young of an age.

Why do some dreams have to be nightmares? I have been killed and toture in some dreams but I don't see them as nightmares, just dreams.

If one does not want to dream in a certain way then one should learn to control their dreams. Easier said than done.

Posted 25 February 2013 - 10:35 PM

Fears aren't there for us to just fear them, nor for us to open ourselves all vulnerable to them. Nor for us to keep running from them. Fears are for us to surpass them. It's a process of growing up. Some may be traumas, but then it's just a bigger and bigger step for you. Size changes, the principle stays the same.

"Dreams are not just for dreaming, but for living them out." Onizuka Eikichi, 22, my favourite anime.
Madness is just a word that's an obscure label. A label for a wide arc of different states of mind. My madness as you might call it, has a method to it. It may seem like madness from your eyes, but from here, the more you get known to yourself, the better it feels.

A webpage about Sleep Paralysis and Associated Hypnagogic and Hypnopompic Experiences.
Physiological symptoms of sleep paralysis are the same with those of syncope. Thus, sleep paralysis is caused by syncope. For experts in cardiovascular diseases, sleep paralysis or syncope is a common symptoms of cardiovascular disease【1】. For a long time, due to the ignorance of physiological knowledge of syncope , ischemie cerebrale ,palpitations and so on, psychological illusion in people’s sleep generated by such physical symptoms i.e. the nightmare really has puzzled the psychologists, therefore they put forward a wide range of wrong even absurd views on the nightmares, which both have no scientific basis, and could not be confirmed, even more were not self-consistent. For example, a medical expert Debacke drew the correct conclusion that the anxiety-dream resulted from ischemie cerebrale according to the physiological symptoms of the anxiety-dream of a boy of thirteen. Freud called such view was a " medical mythology" in the book of Dream Psychology. Most important,the experiment confirmed the idea. For example, a place in country , there is a "haunted" bed which makes people have sleep paralysis or syncope every night, and it is this fact that the pillow in the bed is too high will reduce cerebral blood flow.                                         【1】 http://www.medhelp.org/posts/Sleep-Disorders/Nocturnal-fainting/show/11612

Under what evidence can you be certain that dreams are caused by heart palpitations? You are establishing a direct causal link, but I'm curious as to under what grounds.

(^ regarding nightmares causing heart palpitations) Considering that nightmares often provoke a 'fight or flight' response, adrenaline is often released which in turn can cause heart palpitations, I have to disagree. May I ask what is your logic for disagreeing with this statement?

Not meaning to rip you apart, just curious :)
